Description
Name: skR10005 Date: 08/30/2002
The following JCK1.4a test
api/java_lang/Class/index.html#ForName2[Class2158]
api/java_lang/Class/index.html#ForName2[Class2166]
fails on jdk1.4.0 under plugin.
Java API spec for method Class.forName reads:
"ExceptionInInitializerError - if the initialization provoked by this method
fails"
But implementation throws java.lang.NoClassDefFoundError.
It looks like class loader cashes not loaded class
but the reason is not taken into account.
To reproduce the failure do the following:
1) create java & html files in the same directory.
================test.java===================
public class test extends java.applet.Applet {
public void start() {
try {
Class.forName("Noninitializable");
} catch(ClassNotFoundException e) {
System.out.println("" + e);
return;
} catch(ExceptionInInitializerError eiie) {
System.out.println( "OKAY" );
}
try {
Class.forName("Noninitializable");
} catch(ClassNotFoundException e) {
System.out.println("" + e);
return;
} catch(ExceptionInInitializerError eiie) {
System.out.println( "OKAY" );
}
System.out.println("ExceptionInInitializerError is not thrown");
}
}
class Noninitializable {
static int i = 1/0;
}
================test.html===================
<html>
<APPLET code="test.class" codebase="." width="500" height="500">Java
applet.</APPLET>
</html>
============================================
2) compile java source
$javac -d . test.java
3) run appletviewer
$appletviewer -J-showversion ./test.html
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
OKAY
java.lang.NoClassDefFoundError

at test.start(test.java:12)
at sun.applet.AppletPanel.run(AppletPanel.java:355)
at java.lang.Thread.run(Thread.java:536)
That is the first attempt to load class passed (correct exception is thrown).
The second one is failed.
Note that jdk1.4.1, jdk1.4.2 have the same problems:
$ appletviewer -J-showversion ./test.html
java version "1.4.1-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-rc-b20)
